BURNER.

Application filed .iui so.

To all whom it may non-own I Be it known that 1. WILLIAM W. lit-awn. a citizen of the United States of America. residing at Mansfield, in the county of Richland and filtate otOhio. have invented certain new and useful ln'iprovements in Buruers, of which the following is a specification. .This invention relates to a burner for burning powdered coal or gaseous fuel.

It is well knonui to those skilled in the art of burningpowdered coal fuel that difficulti'es are encountered in procurnn; complete and proper comlnistion oi the powdered fuel as the constituent. component particles thereof areso small or inlinitesimal as to rnake the powdered fuel extremely light inspecific gravity. therefore. due to the fact that the powered fuel must be constantly fed into the furnaces through the medium of an air hlast or the like some of the particles or portions thereof when not under control andthoroughly mixed androtated, diffused and scattered to admit of instant combustion when. subjected to the flames and heat. of the furnace waste and improper combustion of the fuel naturally resulsand there is also an excess of unconstunecl carbon and an excess of slag: and other dhris which accumulates in the furnace causing. in the case of metal lnrgical furnaces, impurities and defects in the metal heated, as well as creating an ex 'cess amount of smoke and dirt in and surrounding the furnace.

It is further well known that unless prop-- hen'hnrner or pipe connections in a directand unhroken line from the mouth of the delivery. end of the humor or the like thereby: focusing an intense heat at one point within the tux-mice in ad of scattering and diffusing the incl so as to produce a uniform heat throughout the interior of the furnace which chucked in my invention by imparting a revolving or rotating motion to tubular meui- 1920.

the air and incl at the delivery end of the burner or the like thereby accelerating its proper and instant comhustion by the llumcs in the furnace -slistcd by the radianl heat from the refractory walls of the furnace.

in the conventional type of burner now in use the flow velocity of thefuel into the furnace under air pressure is direct. continuous and without means of rotating or revolving: the fuel as it emitted direct from the delivery end of the burner into the turnace instead of suspending or retarding the travel of the fuel, and also rotating. dil'lus ing and scattering the powdered coal or other fuel throughout the interior of the furnace as is the case inthe use of the present invention which subjects the fuel to the heat and flames of the furnace for combustion purposes for a longer period of time than is possible with the type of burner nowin use. a

The primary object of the present invention is to design and construct a huruer that will deliver powdered coal or other like fuel into the furnacein such a manner as to impart a whirling rotating or revolving and dill'using motion to the fuel thereby retarding its travel in the furnace. scattering and keeping the fuel in suspension for louircr periods of time at diflcrent locations within the furnace to provide for more perfect and cllici ut comhustion ol' the fuel than can he obtained by the use of a couventionhl type 01 burner. Y

Another oh-ject of the present invention is lo'l'irovidc a burner that is etlieient in operation and economical in the use of fuel.

further ohicct is to construct a. luu-ncr that. will produce a whirling. revolving. si-atlcriug and di'ti'using motion of the fuel at the delivery end of the burner in the same. or opposed directions or combinations thereof.

An ther object of the present invention is to provide means of producing a concentric series or steps of whirling: motions'of the fuel and air-of dillerent diameters or radii in the same. or opposed directions or com-' hiuations thereof.

A further object is to provide a means of swinging the burner and doors of the for nace to either closed or open positions in either direction and afford facilities for-permitting the slag.-'dirt or debris to drip from the 'furnace without opening the main doors of the furnace or affecting" the burner.

COFFEE YERCOLATOR.

Application filed December 19, 1922. Serial No. 607,870.

T all whom it may concern.

Be it known that I, ROBERT J. LENERVILLE, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of lVashington, have invented certain new and useful Improvements in Coffee Percolators, of which the following is a specification. I

This invention relates to improvements in coffee percolators and has as its general object to provide a percolator bythe use of which coffee of a more pleasing aroma and devoid of the usual after effects may be prepared.

More specifically, it is the object of the invention to provide means for supporting the lid of the percolator in an elevated position above the body of the percolator, I having found that in this manner coffee of better aroma and free from its alleged injurious constituents, can be prepared.

In the drawings:

Figure 1 is a vertical sectional view through the percolator embodying the invention Figure 2 is a horizontal sectional view on the line 22 of Figure 1 looking in the direction indicated by the arrows. I

In the drawings, the body of the percolator is indicated in general by the numeral 1 and is provided with the usual handle 2, spout 3, and mouth 4:. The usual hollow perforated base 5 is arranged upon the bottom of the body 1, and the'usual tube 6 leads upwardly from this base in communication at its lower end therewith and to a point substantially level with the top of the mouth a. This tube is provided with the usual collar 7 upon which is supported the fora-minous'cofiee container or basket 8 into which the ground coffee is placed, the container seating within the mouth of the body 1 in the usual manner and having a central tube 9 which is removably fitted onto the upper portion of the tube 6.

The lid of the percolator is indicated in generalby the numeral 9 and the same comprises the usual dome-like center'll which is of glass, and the usual rim 12, which is preferably of metal and surrounds the said center. The present invention contemplates the provision of means for supporting this lid in an elevated position, as illustrated in Figure 1, and as distinguished from the usual arrangement of parts in which the lid is hinged and rests directly upon and closes the mouth 4 of the body of the percolatora In order that the lid may be so supported, arms 13 are secured at their outer ends to the under side of the rim 12 and extend inwardly toward the axis of the lid and are united at their inner ends to a tube 14: which is thus supported axially within the hollow under side of the lid, the upper end of the tube terminating within the upper portion of the dome-like center 11, and the lower end of the tube having united thereto a sleeve extension 15 which isdesigned to be reniovably fitted onto the upper end of the tube 6 and rest at its lower end upon the upper end of the tube 9. It will now be evident that when the parts are assembled and the percolator isplaced on the stove, the boiling water, rising through the tubes 6 and 14, will be discharged through the latter tube into the dome 11 from whence it will drip into the foraminous container 8 and percolate through the coffee therein. In

passing from the interior of the lid to the container 8, the water will necessarily fall through a space which isopen to the atmosphere and it is in this manner that I obtain the desired results.

It will be understood, of course, that the lid is readily removed from the tube 6 when it becomes necessary toreplenish the coffee in the container 8.-

Having thus described the invention, what is claimed as new is:

1. In a percolator, the combination with a body vessel, a water conducting tube extending upwardly therein, and a foraminous coffee container supported upon the tube within the mouth of the vessel, of a hollow dome-like lid, and a tube supported therewithin and removably fitted to the upper end of the first-mentioned tube. V

2. Ina percolator, the combination with a body vessel, a water conducting tube extending upwardly therein, and a foraminous cofltee container supported upon the tube within the mouth of the vessel, of a hollow dome-like lid, a tube disposed in axial alinement with the lid and having an open upper end, terminating within the said lid, and
